 * Mpp Metadata definition
 *
 * Metadata is for information transmision in mpp.
 * Mpp task will contain two meta data:
 *
 * 1. Data flow metadata
 *    This metadata contains information of input / output data flow. For example
 *    A. decoder input side task the input packet must be defined and output frame
 *    may not be defined. Then decoder will try malloc or use committed buffer to
 *    complete decoding.
 *    B. decoder output side task
 *
 *
 * 2. Flow control metadata
